non-incremental/QF_BV/brummayerbiere3/maxand032.smt2 

Propagating bounds through logical operators (unsigned context).
The maxAND(a, b, c, d) algorithm computes the maximum of x & y, where
a <= x <= b  and  c <= y <= d.

From the book "Hacker's delight" by Henry S. Warren, Jr., page 61
We verify that the result is indeed the maximum.
